The Jacksonville Sheriff's Office posted an image of a cruiser trunk packed full of bedding and supplies, with the caption:

"When you leave for work and you don't have any idea when you will be back home. You are prepared that your police car is now your bed. You have enough food and clothes to be self sustained for 72 hours. JSO is ready for Hurricane Irma. We are here for you!"

The Sarasota Police Department rescued a stranded woman and transported her to a shelter.

Officers with Gainesville Police Aviation, obviously unable to take the helicopter out, wrote that they had switched to "playing the role of tree and chainsaw crew through the storm."

The Gainesville Police Department posted a picture showing hundreds of officers prepared to respond to the storm.

"Hundreds of officers have left their families at home to serve and protect you! We are here if you need us and will be out until the sustained winds keep us inside for safety.We are ALL on the same team."

The Hernando County Sheriff's Office posted an image showing deputies helping at area shelters -- washing dishes and serving coffee to evacuees.
